MOTOR-VEHICLE HEATER.

Specification of Letters Patent,

Application filed January 5, 1318. Serial No. 210,448.

To all 'tU/LOI'I/ it may concc'rn:

Be it known. that 1, R111 1 BAnnn'r'r, a citizen of the United States, residing at Leonard, in the county of Fannin and State of Texas, have invented certain new and useful Improvements in Motor-\""ehicle Heaters, of which the following is a specification.

This invention relates to new and useful improwments in heaters for motor vehicles. It is proposed to convey the exhaust gases from the mufller to a container capable of inflation and to inflate said container whereby a heating or warming element for the passengers of the car is provided. The exhaust gases after inflating the container pass from the same.

In carrying out the invention a flexible container is connected with the niufller and receives the warm exhaust gases. The container is connected with an outlet. or discharge which includes a pressure regulator which does not release said gases until the container has been inflated; acting to maintain the inflation during operation. The container may assume the form oi a pillow, a lap robe or other structure.

The invention will be more readily understood from a reading of the following specification and by reference to the accompanying drawings, in which an example of the invention is illustrated; and wherein,

Figure l is a perspective view showing a portion of the floor of a motor car and a heating apparatus constructed in accordai'ice with this inventirjin, the container having the form of a pillow,

Fig. 2 is a sectional view of the same,

Fig. 3 is a view similar to Fig. 1 showing the container in the form of a lap robe, and

Fig. 4 is a sectional view of the same.

In the drawings the numeral 1 designates the floor of an automobile under which the usual mufller 2 is suitably supported. In applying this invention a pipe 3 is connected to the exhaust muttler and carried up through the floor 1. A cut-out valve 4 is included in said pipe and may be adjusted to release the gases when it is not desired to use the heater.

The pipe terminates in a nipple 5 which enters a container 6, the latter having a contracted neck receiving said nipple and being clamped thereon by a split ring 7.

The container 6 is constructed of suitable flexible material of such a nature as to be inflatable, lire proof and capable of retaining the gases supplied to the same. \Vhcn in- Hated it has the form of a pillow. The container should be constructed of suitable lire proof cloth which is impervious to air. At its opposite end the container also has a contracttul neck portion receiving an outlet nipple 8 and being clamped thcreon by a split ring 9. The nipple enters a suitable pressure regulating val e 10 which may be of any approved construction. An exhaust pipe 11. leads from this valve. The object of the valve is to obstruct the escape of the gases until the container has been inflated and to hold said container so inflated, thereby permitting only the excess to escape.

In Figs. 3 and i I have shown the same parts with the exception of the container (3 which in this case assumes the form of a lap robe 12. In order to prevent the walls of: the lap robe from distending the are con nected at intervals by rivets 13. Otherwise the parts are the same with the exception of the. shape of the pipes.

It is obvious that the heated gases passing from the niutiler 2 will enter the container l3 or lap robe 12. as the case may be, and inflate the same whereby these containers bccome heating elements. After a certain inflation and a predetermined pressure has been reached the excess gases will pass the valve 10 and escape from the pipe 11, but the container will remain inflated. The container will sup l v ample heat for warming purposes ant in warm weather may be removed from the car and easily replaced when desired. This flexible structure will be much more eon'ifortable than one of a rigid nature.

The foregoing description and illustration clearly express the invention, but it is to be understood that said illustration is merely an exemplification and the invention may be carried out in various other ways.

What I claim, is:

In a motor vehicle heater for passengers, the combination with the exhaust pipe from the engine. of a supply pipe leading from the exhaust iipe up through the floor of the vehicle. a eXible container adjacent the floor of the vehicle and connected at one end with the supply pipe, a controlling valve in eluded in the supply ipe adapted to permit of the inflation or de ation of the container, said container being inflated by the gases from the exhaust pipe, an outlet connection on the opposite end of the container from the supply pipe, at discharge pi e leading from the outlet down through tl ie floor of the vehicle, and a pressure regulator ineluded in the outlet pipe set to withstand the pressure of the gases to a certain degree, whereby the container is inflated and to re lease the gases through the outlet when the pressure exceeds said degree.

In testimony whereof I afiix my signature.
